Roof Louver Vent

Roof louver vent adopts three-layer rainproof design. The unique structure makes the effective ventilation area and lighting area of the natural ventilator significantly increase. By guiding the indoor hot air to move diagonally upwards, it reduces the energy loss of air flow. Significantly improve the ventilation efficiency. Among them, the third layer of rainproof board receives rain and fog, effectively preventing rain in strong wind and rain, and is suitable for occasions with heavy wind load and high rainproof performance.


Smoke vent louvres adopt  the technology of holistic waterproof structure, which has a more guaranteed waterproof life and avoids the leakage problem caused by silica gel.
